Melons (Cucumis melo)

    southwest Asia
  • Watermelons originated in ____________
  • Water source during droughts
  • Characteristics
  • Warm season
  • Separate male and female flowers
  • Need bees for _______________ wind not
  • Vining growth habit
  • Can be divided into muskmelons, winter melons,
    and _______________

  • Muskmelon (Cucumis melo var. reticulatus)
  • Name comes from the musk _________ of the mature
  • Outer appearance
  • Generally has netted rind with deep ____________

Immature muskmelon
Melon Culture
  • Planting
  • Muskmelons are usually started as
  • Do not transplant well if the roots are disturbed
  • Start the transplants in individual containers
  • Timing of planting
  • After danger of ____________ has passed and the
    soil has warmed and dried

Melon Culture
  • Black plastic mulch
  • _____________ early season growth
  • Controls weeds
  • Install the _________________ mulch 2 to 3 days
    before planting
  • Make sure the ground is ____________
  • Weigh the edges of the mulch down
  • Makes holes every 2 to 3 feet and transplant
    melons into holes

  • Muskmelon, cont.
  • Interior flesh
  • _________ to orange-colored flesh

Harvesting Melons
  • Muskmelons are mature when
  • __________ changes from green to tan-yellow
    between ___________
  • Stem should easily separate (slip) where the
    ________ attaches to the fruit
  • ______________ layer forms between stem and fruit

Melon Problems
  • Subject to damage by
  • Cucumber beetles
  • Bacterial wilt
  • Root knot ___________
  • Commercial growers may control by fumigation
    with __________ bromide

Melon Problems
  • Poor flavor due to
  • Cloudy weather during ripening
  • Like hot, dry weather during ripening
  • Too much or too little water
  • Dont like wet feet
  • Temperatures too high
  • Like mean temps of 65-75F
  • Over or under ripe
  • Often hard to tell changes are subtle

  • Generally grown in the southwest or Europe
  • Fruits are round to oval shaped
  • Inner flesh has strong flavor
  • Outer appearance
  • Non-sutured, heavily netted
  • Yellow colored when mature

Winter Melon (Cucumis melo var. inodorus)
  • Smooth rind surface
  • Do not separate from the vine when ripe
  • Lack a distinctive odor
  • Require long growing season
  • 3-5 months

Harvesting Melons
  • Honeydew and Crenshaw melons are mature when
  • They turn completely yellow
  • Blossom end is slightly soft to the touch
  • They need to be cut off the vine because they do
    not slip

Winter Melons
  • Examples
  • Honeydew
  • Inner flesh
  • Sweet, mild, and firm flesh
  • Flesh has a light green color
  • Outer appearance
  • Smooth, white rind

Winter Melons
  • Orange Flesh Honeydew
  • Is a cross between the cantaloupe and honeydew
  • Crenshaw
  • A popular melon
  • Inner flesh
  • Golden pink flesh
  • Tastes like honeydew
  • Outer appearance
  • Smooth skin
  • Creamy white with a little yellow when mature

Winter Melons
  • Casaba
  • Outer appearance
  • Deep yellow at maturity
  • Inner flesh
  • Creamy white flesh
  • Pear-like texture

Winter Melons
  • Juan Canary
  • Latin American in origin
  • Inner flesh
  • Has a sweet white flesh with a pink blush around
    the seed cavity
  • Tastes like a mild cantaloupe
  • Outer appearance
  • Rough surface with ridging
  • No netting

Winter Melons
  • Galia
  • Mediterranean origin
  • Inner flesh
  • Green flesh
  • Strong melon flavor
  • Outer appearance
  • Honeydew type
  • Round shape
  • Yellow color when mature

Muskmelons vs. Winter Melons
Muskmelon Winter Melon
Locally grown (Cantaloupe is version grown in southwest) Grown in southwest (and other warm climates)
Musky flavor Do not have a musky flavor
Detach from stem when pulled Must be cut from plant
Turn yellow when ripe May or may not turn yellow when ripe

Watermelons (Citrullus lanatus)
  • History
  • Originated in Africa
  • Brought to Europe in 16th century
  • Appearance
  • Serrated leaves

  • Fruit appearance
  • Flesh color
  • Most watermelons are red color
  • Some cultivars have a yellow flesh

  • Fruit appearance
  • Shape
  • Standard shape is oblong
  • Icebox types
  • Small round watermelons with a dark skin
  • Easier to grow
  • Mature rapidly
  • Smaller plants

  • Seedless watermelon
  • For seedless watermelon to set fruit you must
    also plant a normal diploid (seedy) cultivar in
    with the tetraploid seedless watermelons
  • Produces self-sterile triploid hybrids which
    develop normal looking fruits but no fully
    developed seeds

Watermelon Culture
  • Adaptation
  • Watermelon are more adapted to the south than to
    central or northern Illinois
  • Under short seasons, watermelons do not produce
    enough sugar and are not sweet
  • Ways to overcome
  • Select early cultivars
  • Grow icebox types
  • Use transplants
  • Use plastic mulch

Watermelon Culture
  • Watering
  • Watermelon have moderately deep root systems
  • Watering is seldom necessary unless weather turns
    dry for a prolonged period
  • Spacing
  • Watermelon vines require considerable space
  • Space hills 6 ft. apart, with 7 to 10 ft. between

Watermelon Culture
  • Can overcome space constraints
  • Train vines onto a trellis
  • Fruits must be supported by nets or bags

Harvesting Watermelons
  • How to tell when watermelon fruit is ripe
  • Curly tendrils on stem near the point of
    attachment dry down
  • Surface color turns dull
  • Skin becomes resistant to penetration by a
    thumbnail and is tough to the touch
  • Bottom of melon (where it touches the ground)
    turns from light green to a yellowish color

Watermelon Problems
  • Problems
  • Birds will makes holes in tops of watermelons
  • Netting can be used to prevent the problem
